Shaving down there ?

My friend wants to shave and she was reading a lot of articles and stuff and “shaving sideways “ “ under water “ “ shave with coconut oil moistures with cocount oil “ “ use baby oil to shave “ “ use olive oil to shave “ but these things all clog your pores and can give you infection for eg. Yeast infections ph imbalance , odor, razor bumps, bv and the list goes on. How to shave without getting razor bumps and with what and how to and just everything because she’s fed up 😭 and I don’t know how to help. Shaving cream leaves your area stubble please help me. Like how do you shave side ways down ways ? What about your inside ? Like labia and lips and so on. She can’t get waxed because her age and her family and hair removal creams says not to use on your genitals and it smell like perfume so it can cause infections.
